Introduction: Drawknife, How to Make
Hello, in this project I show you how to make
First of all, I apologize for my lack of words, I still have to learn a lot. My mother tongue is not English and I am still learning. Thanks to all of you who are correcting me and helping me to learn. If you see any error, do not hesitate to correct me.

Ø How I did my Drawknife and my tools:
• Column drill
• Belt sander
• My forge (you can see how I made it on my channel)
• Oven in my house
• Coarse grain stone
• Grain stone 3000 and 8000
• D2 steel 500 x 30 x 6 mm
Chemical composition: C (1.55) Mn (0.40) Si (0.40) Cr (12) Mo (0.75) V (0.75)
Step 1: Design:
Let´s go. The first thing I did was draw my
Drawknife, I gave the sheet 200mm with a curve of 16mm in diameter and I finished the shape making a diagonal up to 8mm from the end.
Step 2: Cut:
I made the drilling with the 16mm column drill
and then I finished the cuts with the radial. I am boring with the drill to save cutting time with the radial and discs.
Marking a line parallel to the edge that will be the edge of 15mm, I start roughing with my belt sander with a grain of 36 sandpaper, to take the desired shape and finish smoothing the bottom with the same sandpaper.
Step 3: Roughing:
Marking a line parallel to the edge that will
be the edge of 15mm, I start roughing with my belt sander with a grain of 36 sandpaper, to take the desired shape and finish smoothing the bottom with the same sandpaper.
Step 4: the Shape of the Handles:
I turn the forge and heat red hot the widest
part of the handles, with the help of a tool that I have manufactured with an angle of iron of 40 x 40 mm and some support screws where I wanted it to bend, help me with a steel bar, to pry and get the two sides equal.
In this part of the project is where I am experimenting more, due to I am not an expert in the forge, I must say that everything is done with the videos and things I can read I read.
If there is something wrong, please, do not hesitate to tell me, I would like to learn from my mistakes.
Step 5: Heat Treatment:
Normalized steel, putting it red-hot and letting cool one hour by itself.
The tempered I put it to the alive red also until it loses the polarity, that I check with a magnet and I maintain it a minute more inside the forge, cooling it with oil.
Annealing I have one hour at 200 degrees, 10 minutes for each millimeter of thickness.
Step 6: Handles:
For the Handles, I use a piece of olive tree,
with stainless steel rings. It is the first time I use the lathe, I am not very loose the subject of the rings, weighed that they would adjust when putting the tool, but it was not to I shave the handle and I have to do it again.
Then I made a 6mm hole in the part of the steel ring and finished it with a pair of hands of flaxseed oil
Step 7: Finishing and Sharpening
Review with 400 sandpaper the bottom of the
blade and the edge.
I start to get the edge with a basic Stanley stone and I finish it with a 3000 and 8000 grain stone, always using water to facilitate the sharpening
I place the handles with the help of a mallet
and it was ready to try it and enjoy it!
I hope you like it, any mistakes with the
vocabulary, please do not hesitate to tell me to improve.
